LUBRICATING DEVIICE.

Application filed May 6, 1925. Serial No. 28,481.

To all whom it may concern:

Be it known that I, ALVIN THoRNBRUoH, a citizen of the United States, residing at Manly, in the county of Worth and State of Iowa, have invented a new and useful Lubricating Device, of which the following is a specification.

This invention aims to provide novel means for the lubricating of all journals under all classes of cars, locomotives, locomotive tenders and other vehicles, and to improve generally and to enhance the utility of devices of that kind to which the inven- 7 tion appertains.

Figure 1 shows in vertical section, a device constructed in accordance with the invention; Figure 2 is a cross section on the line 22 of Figure 1; Figure 3 is a horizontal section; Figure 4 is a plan of the bearing; Figure 5 is a plan of the pan.

The numeral 1 marks a casing, and the numeral 2 designates the axle of a freight car or any other vehicle, the axle extending into the casing and cooperating with a bearing 3 held in place by any suitable securing means 4 known in the art. 7 There is a guide 5 in the rear end of the casing 1, wherein operates a closure including a slide plate 6 carrying a packing strip 7 fitting closely about the axle 2, the axle passing through the closure and through an opening 8 in the rear end of the casing 1, the packing strip 7 preventing dirt from entering the casing 1.

A trough-shaped pan 9 is located below the axle or rotatable member 2, the end walls of the pan being in the form of seats 10 for packings 11 which prevent a leakage of oil from the pan when the pan is thrust upwardly by a compression spring 12 abutting against the bottom of the casing 1 and against the bottom of the pan 9, the spring being retained in place by bosses 14 on the pan and on the casing. The pan 9 has a transverse oil pocket 15 into which dips a distributor ring 16 receiving the axle 2 and ceived rotatably) has diverging oil grooves 19 and located on opposite sides of the recess 17 and communicating therewith, the

recess 17 intersecting the concave surface 18 of the bearing, as Figures 4 and 1 clearly show.

The ring 16, being rotated responsive to the rotation of the axle 2, carries up the oil from the pocket 15 and distributes it on the axle 2 within the recess 17 the oil flowing along the grooves 19 and 20 of the hear ing and being distributed to the concaved surface 18 of the bearing, and through the contacting upper portion of the axle 2.

The device shown and described will effect lubrication with decreased cost of oil and will also lengthen the life of parts subjected to wear, hot boxes and like annoyances being avoided. A mechanic can make changes in the form shown, without departing from the spirit of the invention.

I claim In a device of the class described, a casing, a bearing in the upper portion of the casing and provided with a concaved surface intersected by a transverse recess, a rotatable member journaled on said surface, a trough-shaped pan in the lower portion of the casing and having a transverse oil pocket, a compression spring cooperating with the pan and the casing to hold the pan in operative relation to the rotatable member, and a distributor ring running loosely on the rotatable member and extendedinto the pocket and into the recess.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

ALVIN THORNBRUGH.
